Ajax Is About to Embark on a Project Involving the Design

Essay

Ajax is about to embark on a project involving the design, manufacture, and introduction of a new microwave oven.The first three activities and the immediate predecessors are: $\begin{array}{lcc}&\text { Activity } &\text { Predecessor }\\\text { A } & \text { Prototype Design } & \text { none } \\\text { B } & \text { Acquisition of Materials } & \text { A } \\\text { C } & \text { Prototype Construction } & \text { B }\end{array}$
However, it has not yet been decided whether the prototype materials will be purchased from a vendor (taking two weeks) or produced in another Ajax division (four weeks).What are the implications of this regarding usage of any standard project scheduling technique?
